SUPPLEMENT NO. 7 DATED SEPTEMBER 15, 2026
TO THE PROSPECTUS DATED APRIL 15, 2026
This prospectus supplement (this “Supplement”) is part of and should be read in conjunction with the prospectus of J.P. Morgan Real Estate Income Trust, Inc., dated April 15, 2026 (the “Prospectus”). Unless otherwise defined herein, capitalized terms used in this Supplement shall have the same meanings as in the Prospectus.
The purposes of this Supplement are as follows:
•to disclose the acquisition of a two-building industrial campus;
•to disclose the transaction price for each class of our common stock as of October 1, 2026;
•to disclose the calculation of our August 31, 2026 net asset value (“NAV”) per share for each class of our common stock;
•to provide an update on the status of our public offering; and
•to disclose certain updates to our Prospectus.
Industrial Acquisition
On September 10, 2026, we acquired a 521,091 square foot, Class A, two-building industrial campus in the Los Angeles, California Metropolitan Statistical Area for $176.5 million, excluding closing costs.
October 1, 2026 Transaction Price
The transaction price for each share class of our common stock sold in this offering for subscriptions accepted as of October 1, 2026 (and repurchases as of September 30, 2026) is as follows:
| Transaction Price (per share) | |||||
| Class D | $ | 10.56 | |||
| Class I | $ | 10.61 | |||
| Class S | $ | 11.56 | |||
| Class T | $ | 11.51 | |||
As of August 31, 2026, we had no outstanding Class S shares. As a result, the transaction price for our Class S shares is equal to the NAV per share for our Class E shares as of August 31, 2026. Class E, Class X and Class Y shares are not sold as a part of this offering. The purchase price of our common stock for each share class equals the transaction price of such class, plus applicable upfront selling commissions and dealer manager fees. The repurchase price for each share class equals the transaction price of such class.
August 31, 2026 NAV Per Share
We calculate NAV per share in accordance with the valuation guidelines that have been approved by our board of directors. Our NAV per share, which is updated as of the last calendar day of each month, is posted on our website at www.jpmreit.com. Please refer to “Net Asset Value Calculation and Valuation Guidelines” in the Prospectus for how our NAV is determined. The Adviser is ultimately responsible for determining our NAV.

Our total NAV presented in the following tables includes the aggregate NAV of our common stock, as well as partnership interests of the Operating Partnership held by the Special Limited Partner. The following table provides a breakdown of the major components of our total NAV as of August 31, 2026 ($ and shares/units in thousands):
| Components of NAV | August 31, 2026 | |||||||
| Investments in real estate | $ | 1,558,911 | ||||||
| Investments in real estate debt | 358,599 | |||||||
| Investments in real estate-related and other securities | 14,833 | |||||||
| Cash and cash equivalents | 199,106 | |||||||
| Restricted cash | 7,099 | |||||||
| Other assets | 20,219 | |||||||
| Debt obligations | (968,868) | |||||||
| Other liabilities | (30,050) | |||||||

| Net Asset Value | $ | 1,140,485 | ||||||
| Number of outstanding shares/units | 100,917 | |||||||
(1) Stockholder servicing fees only apply to Class T, Class S, Class D and Class Y shares. For purposes of NAV, we recognize the stockholder servicing fee as a reduction of NAV on a monthly basis as such fee is paid. Under accounting principles generally accepted in the United States of America (“GAAP”), we accrue the lifetime cost of the stockholder servicing fee as an offering cost at the time we sell Class T, Class S, Class D and Class Y shares. The stockholder servicing fee on Class D shares was waived as of August 31, 2026, and the NAV attributable to current holders of Class D shares will not be included in the computation of stockholder servicing fees charged on Class D shares in perpetuity. As of August 31, 2026, we had accrued under GAAP stockholder servicing fees of $8.6 million.
The following table provides a breakdown of our total NAV and NAV per share/unit by class as of August 31, 2026 ($ and shares/units in thousands, except per share/unit data):
| Share Class/Unit | Net asset value | Number of outstanding shares/units | NAV per share/unit | |||||||||||||||||

Set forth below are the weighted averages of the key assumptions in the discounted cash flow methodology used in the August 31, 2026 valuations, based on property types. Once we value more than one single-family rental property or more than one office property, we will include the key assumptions for such property type.
| Property Type | Discount Rate | Exit Capitalization Rate | ||||||||||||
| Multifamily | 7.35 | % | 5.88 | % | ||||||||||
| Industrial | 7.93 | % | 6.43 | % | ||||||||||
| Retail | 7.52 | % | 6.63 | % | ||||||||||

These assumptions are determined by our independent valuation advisor and reviewed by the Adviser. A change in these assumptions would impact the calculation of the value of our property investments. For example, assuming all other factors remain unchanged, the changes listed below would result in the following effects on our investment values:
| Input | Hypothetical Change | Multifamily Investment Values | Industrial Investment Values | Retail Investment Values | ||||||||||||||||||||||
| Discount Rate | 0.25% decrease | 1.92% | 1.94% | 2.00% | ||||||||||||||||||||||
| (weighted average) | 0.25% increase | (1.87)% | (1.85)% | (1.82)% | ||||||||||||||||||||||
| Exit Capitalization Rate | 0.25% decrease | 2.67% | 2.44% | 2.28% | ||||||||||||||||||||||
| (weighted average) | 0.25% increase | (2.47)% | (2.22)% | (2.09)% | ||||||||||||||||||||||
